The May 4th Movement originated as a student protest in Beijing in 1919 against the Treaty of Versailles, which gave Japanese control over Shandong province. The protests sparked a nationwide movement calling for political and social reforms and a rejection of traditional Confucian social values. Intellectuals promoted new ideas from the West and published radical works criticizing China's past. This helped launch the New Culture Movement, where thinkers debated reforms like embracing political ideologies like Marxism or adopting a more pragmatic approach.
